Arxiv: A Census of Photometrically Selected Little Red Dots at 4 < z < 9 in JWST Blank Fields Published: 1/18/2024 3:52:43 PM Updated: 4/14/2024 10:16:26 PM
Paper abstract: Observations with the James Webb Space Telescope (JWST) have uncoverednumerous faint active galactic nuclei (AGN) at z~5 and beyond. Theseobjects are key to our understanding of the formation of supermassive blackholes (SMBHs), their co-evolution with host galaxies, as well as the role ofAGN in cosmic reionization. Using photometric colors and size measurements, weperform a search for compact red objects in an array of blank deep JWST/NIRCamfields totaling ~640 arcmin^{2}. Our careful selection yields 260reddened AGN candidates at 4
